I have just installed LMDE and updated to the newest packages. In the logout menu, I have "Bereitschaft" (suspend) and "Ruhezustand" (hibernate). But when I hibernate, my machine halts. When I switch it on again, it boots from scratch.

I previously used Mint 10 Julia, and hibernating worked perfectly.

I have a swap partition large enough; it is registered in /etc/fstab, but it is not mounted!?

It isn't really mounted like other file systems and doesn't appear in 'mount' for me either. My fstab has the swap partition listed with mount point 'none' although I have seen it written as 'swap' in the past I don't know if this is significant, but you could try changing it and see.

Although it is a bit old now, there is an enormous amount of information on swap partitions and usage here:

With the UUID being that of your swap partition. You can test this from grub by typing this entry at the end of the grub line starting with the word 'linux' then pressing f10 to boot then trying the hibernate. If it works you can add it to /etc/default/grub

Swap was already there (and shown with 'free'), but it was not used for hibernating.

Do you think I should file this as a bug report? The "normal" Linux Mint edition (whose partition layout I imitated when installing LMDE) uses available swap for hibernation by default. So somehow the LMDE installer forgets to do this.

Hmm, as I wrote earlier, I previously used "Normal" Mint 10 Julia on the same system, and hibernating worked perfectly.

When I installed LMDE 1204, gparted popped up at some point, and I played a little bit with it, that is, I created and deleted partitions until I decided to give it the same structure as Mint 10 Julia: If you give the "normal" Mint installer a whole, empty hard drive to eat, It creates one huge partition for everything and one tiny extended partition of about 2.5 times the size of your main memory filled with the according swap partition in it. And hibernating works out-of-the-box.

So I conclude that the quirk is not in my system, but in the LMDE installer. (?)

Can it be due to the fact that my huge partition is called /dev/sda1, and the tiny ones /dev/sda4 and /dev/sda5 (which comes, I suppose, from playing around with gparted)?
